This is why I don't attempt aircraft paintings, my hide is too thin. However, as Russel has rhinohide I'd like to point out that the horizontal stabilizer on the DH2 was parallel to the top booms so that when it was on the ground it had the same down angle as the booms did. See these pics for a good view of them in flight and on the ground.

My point is that I don't get the impression from Russel's painting that the horizontal stabs have the appropriate downsloping angle.
That's all, I'll go now.
Love the painting BTW Russ.
